Length-weight relationship of five serranids from Palawan Island, Philippines

The parameters a and b of the length-weight relationship (LWR) of the form W=aLb are presented for five species of serranids belonging to the genus Cephalopolis. The fish samples used for the study were caught by hook and line, fish corrals, and spearguns during August 1995 to December 1998 from the waters around Palawan Island, Philippines. Information on the LWR of six fishes from other studies conducted in Palawan is also provided.

Community-based marine protected areas in the Bohol (Mindanao) Sea, Philippines

This paper discusses the status, direction and management issues in the marine protected areas (MPAs) of the Bohol (Mindanao) Sea, Philippines. The MPAs in the study area have increased through the years. Many of them were established and managed by the local government units (LGUs) in collaboration with national government agencies (NGAs), academic institutions, people’s and non-governmental organizations (NGOs). Several management issues and problems were cited by the MPA managers such as insuffi cient funds and facilities, lack of support from NGAs/NGOs and lack of education among the people. Nevertheless, lessons for sustainability can be learned from the experience of some wellmanaged MPAs in the Bohol Sea. These include strong support from the political leadership, community participation and networking among the concerned sectors. Although the best practices are being followed in a number of MPAs in the Bohol Sea, success is still fragmented. The MPAs are currently managed independently although there are ongoing initiatives to network their efforts. However, it can be observed that, as a management tool, MPAs are gaining popularity and support, not only among the fisherfolk but also among local communities and LGUs in the Bohol Sea area.

Mangrove rehabilitation and coastal resource management: a case study of Cogtong Bay, Philippines

The Cogtong Bay experience represents a bold attempt to pursue a shared responsibility between the government and local residents for rehabilitating coastal resources. Some of the factors that provided the impetus to co-management arrangements were the recognition of resource management problems, dependence on coastal resources for livelihood and the desire for more sustainable resource use. This paper draws attention to the importance of legitimate user/property rights, vigilant law enforcement efforts, common commitment among stakeholders and continuing support from local leadership in viable co-management arrangements.

Length-weight relationship of fishes from a seagrass meadow in Negros Oriental, Philippines

The parameters a and b of the length-weight relationship of the form W=aL super(b) were estimated for 13 fish species sampled in a seagrass meadow in Negros Oriental, Philippines. Also, to facilitate conversions, the relationship between total length and standard length for the 13 species is given.

Measuring transaction costs of fisheries co-management in San Salvador Island, Philippines

It is generally accepted that co-management systems are more cost-effective than centralized management of natural resources. However, no attempts have been made to empirically verify the transaction costs involved in fisheries co-management. Some estimates of transaction costs of fisheries co-management in San Salvador Island, Philippines, are presented in this paper. These estimates are used to compare the various transaction costs in co-managed and in centrally managed fisheries in San Salvador Island.

A global experiment on tilapia aquaculture: impacts of the Pond Dynamics/Aquaculture CRSP in Rwanda, Honduras, Philippines and Thailand

The Pond Dynamics/Aquaculture Collaborative Research Support Program (PDA/CRSP) is a global research network to generate basic science that may be used to advance aquaculture development. One of a family of research programs funded by the United States Agency for International Development (USAID), the CRSP focuses on improving the efficiency of aquaculture systems. The PDA/CRSP began work in 1982 in Thailand, and subsequently in the Philippines, Honduras, the US and, until recently, Rwanda. At all the sites, the goal is the same: to identify constraints to aquaculture production, and to design responses that are environmentally and culturally appropriate. The research network's global experiment has focused on tilapia (Oreochromis niloticus), although some sites have devoted attention to marine shrimp and other locally significant species. Impact of the network's investigations with tilapia is examined in this article.

Economic policies and the sustainable development of coastal resources in the Philippines

The link between environmental trends and economic policies is examined. The assessment of the past and present economic policies affecting the use of coastal resources in the Philippines showed that these policies have accelerated the rate of degradation of coastal resources. The current situation demands not only the reorientation of economic policies, but also other related actions to attain sustainable development of coastal resources.

Diet composition and daily ration estimates of selected trawl-caught fishes in San Miguel Bay, Philippines

The diet composition of fish caught in San Miguel Bay, Philippines, in April and May 1993 was studied. The diets of tiger-tooth croaker (Otolithes ruber), commerson's anchovy (Stolephorus commersonii); and the Indian anchovy (Stolephorus indicus) consisted mainly of zooplankton, primarily crustaceans. The stomach content of orangefin ponyfish (Leiognathus bindus) was found to consist mostly of detritus and unidentified materials. Daily rations estimated were: 1.90 g day super(1) for O. ruber of 17.3 g mean body weight (BW), 0.078 g day super(1) for S. commersonii) of 3.8 g mean BW, 0.062 g day super(1) for S. indicus of 3.9 g mean BW and 0.56 g day super(1) for L. bindus of 7.7 g mean BW.

Impact evaluation of community-based coastal resource management projects in the Philippines

The benefits of decentralizing the management of coastal resources to local governments and resource users have long been recognized, but the best systems for coastal resources management depend on many factors. A number of community-based management and co-management projects were started in the Philippines in the early 1980s. This report describes a comparative assessment of these projects to determine where improvements can be made in the design of future community-based coastal resource management projects. Early and continuing involvement by project beneficiaries is one of the factors that contributes to the success of the project development, implementation, and evaluation.

The Samar Sea, Philippines: a decade of devastation

Some of the major problems observed after 10 years that lead to resource degradation in Samar Sea are enumerated and discussed.

The cost of action: CRM investment in the Philippines

Knowing the cost of investment in coastal resources management (CRM) is important especially in understanding the cost of undertaking one and ascertaining whether the outcomes are worth the money spent. In the Philippines, various CRM projects have already been initiated and no studies have tried to account for the total level of investment. This paper provides an estimate of money spent or invested on CRM in the Philippines and examines the investment per km2 of coral reefs.
